Will the Thermalright - Ultra 120 eXtreme work on my motherboard?

My friend just helped me build this rig:

Intel Core 2 QUAD Q6600 Quad Core 2.4GHz 8MB(2x4MB) Socket 775

Gigabyte GA-P35-DQ6 iP35 4DDR2-DIMM 2PCI 5PCIe SATA Socket775 ATX

And my old Scythe Ninja won't fit on the motherboard because that silentpipe technology that the gigabyte motherboard uses has a backplate (think thats the right word) right underneath the cpu.

So the cooler im using right now is way to loud and Im really keen on getting the Thermalright Ultra 120 eXtreme but im not sure it will fit since the scythe didn't. Do you guys know if it can be fitted or am I stuck with this thing im using right now?

I think the Ultra has a backplate too. Have you gone on Newegg and looked?

You aren't stuck, since you can get coolers that fit in the same way the stock one does, such as the Arctic Cooling Pro 7.

The Thermalright does use a backplate. I'm not sure how differently configured your Mobo is when compared to mine (gigabyte p35c-ds3r) but I had absolutely no issues with mounting it. My only scare came from my case (antec 900) but once everything was seated it fit, albeit with little or no extra elbow room.
